NixOS must generate audit records when successful/unsuccessful attempts to delete privileges occur.
An XCCDF Rule
Description
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).
